中欧盆地三叠系是典型的海陆过渡相沉积 ,松辽盆地白垩系是含有海侵事件记录的陆相河湖盆地。两盆地的共同特点是 :1大陆克拉通上长期发育的大型坳陷盆地 ;2靠近古大洋和 (或 )有向海通道 ;3主要由互层状泥岩、粉砂岩、碳酸盐岩和膏盐层组成 ;4无典型海相化石 ,可能发育有半咸水和 (或 )高盐度生物 ;5海侵层中自生矿物的 δ34 S,δ1 3C,δ1 8O同位素比值及介质盐度指数 (Sr/Ba)、碱度指数 (Ca+Mg) /(Si+Al)、还原性指标 (Zn+Ni) /Ga、硫沉积通量指数 (归一化硫含量 )等显著高于相邻层位背景值。
The Triassic in the Central European Basin is a typical sedimentary facies of the sea-land transition. The Cretaceous in the Songliao Basin is a continental river-lake basin containing transatlantic events. Common features of the two basins are: 1 Large-scale depression basins over the craton in the Mainland, 2 Close to the Paleocean and / or directed sea passages 3 Mainly composed of interbedded mudstone, siltstone, carbonate and ointment Salt composition; 4 without typical marine fossils, may have developed brackish water and (or) high salinity organisms; δ34S, δ1 3C, δ180 isotope ratio and media salinity index Sr / Ba, Ca + Mg / Si + Al, reduction index Zn + Ni / Ga, sulfur deposition flux index (normalized sulfur content) were significantly higher than those of adjacent layers Bit background value.
